Abstract

The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersible linear sulphonic polyester and at least one modified guar gum, methods employing this composition, and uses thereof.

Description

[0001] This application claims benefit of U.S. Provisional Application No.60/620,335, filed Oct. 21, 2004, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. .sctn. 119 to French Patent Application No. 04 08396, filed Jul. 29, 2004, the contents of which are also incorporated by reference.

[0002] The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersible linear sulphonic polyester and at least one modified guar gum, and the methods employing this composition. The present disclosure also relates to the use, for fixing the hairstyle, of a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersible linear sulphonic polyester and at least one modified guar gum.

[0003] Cosmetic compositions for the shaping and/or form retention of the hairstyle can be in the form of a spray and comprise a solution, generally alcoholic, and one or more components, referred to as fixing components, which are generally polymeric resins, the role of which may be to form connections between the hairs or to sheath the hairs. These fixing components are often formulated as a mixture with various cosmetic adjuvants.

[0004] Cosmetic compositions containing fixing components, as described, are generally packaged either as a pump-action spray or in an appropriate aerosol container pressurized using a propellant. The aerosol system comprises, on the one hand, a liquid phase (or fluid) and, on the other hand, a propellant.

[0005] It is also possible to use such styling compositions in the form of gels, creams or foams.

[0006] Once applied to the hair, it is intended that the fixing components in such styling compositions will make it possible to fix the hair. However, the polymers commonly used as fixing agents in styling compositions often do not make it possible to retain the shaping of the hairstyle when the latter is brought into contact with water for a long period of time, such as, for example, when brought into contact with rain or perspiration or during bathing: sea bathing or bathing in a swimming pool, and the like.

[0007] The present inventors have discovered, surprisingly, that the use of a cosmetic composition comprising, in a cosmetic acceptable medium, at least one water-dispersible linear sulphonic polyester and at least one modified guar gum makes it possible to fix and/or shape hairstyles and/or to retain the shaping of hairstyles when the latter are brought into contact with water for a prolonged period of time. Within the meaning of the present disclosure, this phenomenon is referred to as "resistance to water".

[0008] The term "prolonged period of time", as used herein, is understood to mean being brought into contact with water for a minimum period of time of one minute, such as 10 minutes or, for example, 20 minutes.

[0009] The compositions disclosed herein also make it possible to obtain a hairstyle which is resistant to atmospheric moisture.

[0010] The compositions according to the present disclosure make possible good fixing and/or good form retention of the hair, that is to say, a styling effect which may last throughout the day, indeed even for several days, and/or which may exhibit good resistance to water, such as good resistance to repeated bathing. These compositions may also exhibit the advantage of being removed on shampooing. Overall, these compositions make it possible to confer good cosmetic properties.

[0011] Disclosed herein, therefore, is a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersible linear sulphonic polyester and at least one modified guar gum.

[0012] Also disclosed is a method for the shaping or form retention of the hairstyle in which the above-described cosmetic composition is employed.

[0013] Further disclosed herein is the use of a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersible linear sulphonic polyester and at least one modified guar gum as a styling composition for the fixing and/or the form retention of the hair, such as when it is brought into contact with water for a prolonged period of time, for instance in the case of rain or perspiration or when bathing: such as sea bathing or bathing in a swimming pool. According to this embodiment, the use of the composition makes it possible to obtain a water-resistant hairstyle (wherein "hairstyle" refers to the shaping of the hair). Further, in this embodiment, the cosmetic composition can be provided in a form chosen from lotions, sprays, foams, gels and creams.

[0014] Other characteristics, aspects and advantages of the present disclosure will become even more clearly apparent on reading the description and examples which follow.

[0015] The term "styling cosmetic composition", within the meaning of the present disclosure, is understood to mean a composition for the shaping or form retention of a hairstyle.

[0016] The cosmetically acceptable medium used in the compositions disclosed herein is an aqueous, aqueous/alcoholic or alcoholic medium optionally comprising at least one additional organic solvent. The alcohol may be a monohydroxylated alkanol chosen from lower C.sub.1-C.sub.4 alcohols, such as ethanol, isopropanol, tert-butanol or n-butanol; in at least one embodiment, the alcohol used is ethanol.

[0017] The concentration of alcohol in the compositions according to the present disclosure ranges from 0 to 50%, such as from 0 to 10% or from 0 to 5%, by weight with respect to the total weight of the composition.

[0018] The additional organic solvents which can be used in the compositions according to the present disclosure include polyols, such as propylene glycol, polyol ethers and their mixtures.

[0019] The concentration of additional organic solvent in the compositions according to the present disclosure ranges from 0 to 30%, such as from 0 to 20%, by weight with respect to the total weight of the composition.

Water-Dispersible Linear Sulphonic Polyesters

[0020] As stated above, the composition according to the present disclosure comprises a water-dispersible linear sulphonic polyester. The term "water-dispersible linear sulphonic polyester" is understood herein to mean any sulphonic polyester exhibiting an ability to form a dispersion, that is to say a two-phase system, where the first phase is formed of finely divided particles uniformly distributed in the second continuous phase.

[0021] The term "sulphonic polyester" is understood herein to mean copolyesters obtained by polycondensation of at least one dicarboxylic acid or of one of its esters, of at least one diol and of at least one difunctional sulphoaryldicarboxyl compound substituted on the aromatic ring by an --SO.sub.3M group in which M is chosen from a hydrogen atom and a metal ion, such as Na.sup.+, Li.sup.+ or K.sup.+.

[0022] The water-dispersible linear sulphonic polyesters used in the context of the present disclosure exhibit a weight-average molecular mass ranging from 1000 to 60,000, such as from 4000 to 20,000, as determined by gel permeation chromatography (or GPC).

[0023] The glass transition temperature (Tg) of these sulphonic polyesters may range from 10.degree. C. to 100.degree. C. In at least one embodiment, the Tg of the at least one water-dispersible linear sulphonic polyester used is greater than or equal to 50.degree. C. The glass transition temperature (Tg) is measured by differential scanning calorimetry (DSC) according to Standard ASTM D3418-97.

[0024] The water-dispersible linear sulphonic polyesters useful herein are described in more detail, for example, in U.S. Pat. Nos. 3,734,874, 3,779,993, 4,119,680, 4,300,580, 4,973,656, 5,660,816, 5,662,893 and 5,674,479.

[0025] In at least one embodiment, the water-dispersible linear sulphonic polyesters comprise at least units derived from isophthalic acid, from a salt of sulphoaryldicarboxylic acid and from diethylene glycol. For example, the sulphonic polyesters may be obtained from isophthalic acid, sodium salt of sulphoisophthalic acid, diethylene glycol and 1,4-cyclohexanedimethanol.

[0026] Mention may be made, as examples of water-dispersible linear sulphonic polyesters, of those known under the INCI name Diglycol/CHDM/Isophthalates/SIP and sold under the trade names "Eastman AQ Polymer" (AQ35S, AQ38S, AQ55S, AQ48 Ultra) by Eastman Chemical.

[0027] The concentration of water-dispersible linear sulphonic polyester(s) used in the compositions according to the present disclosure ranges from 0.1 to 40%, such as from 1 to 30%, or from 5 to 25%, by weight with respect to the total weight of the composition.

Modified Guar Gums

[0028] The composition according to the invention comprises at least one modified guar gum.

[0029] The term "modified guar gum", within the meaning of the present disclosure, is understood to mean -guar gums alkylated by at least one C.sub.1-8 alkyl group, guar gums hydroxyalkylated by at least one C.sub.1-8 hydroxyalkyl group or guar gums acylated by at least one C.sub.1-8 acyl group.

[0030] For example, the modified guar gum may be hydroxypropylated guar gum, such as that sold under the name Jaguar HP 105 by Rhodia.

[0031] The concentration of modified guar gum(s) used in the compositions according to the present disclosure ranges from 0.05 to 10%, such as from 0.1 to 5% or from 0.5 to 3%, by weight with respect to the total weight of the composition.

[0032] Advantageously, the water-dispersible linear sulphonic polyester/modified guar gum ratio ranges from 0.01 to 100, such as from 1 to 75 or from 2 to 50.

[0033] he compositions according to the present disclosure can also comprise at least one additional cosmetic adjuvant, such as those mentioned below.

[0034] With respect to fixing polymers as the at least one additional cosmetic adjuvant, any anionic, cationic, amphoteric or nonionic fixing polymer, and mixtures thereof, used in the art can be used in the compositions according to the present disclosure.

[0035] The additional fixing polymers may be soluble in the cosmetically acceptable medium or may be insoluble in this same medium and, in this case, used in the form of dispersions of solid or liquid polymer particles (e.g., latex or pseudolatex).

Generally, the size of the crystals of the wax is such that the crystals diffract and/or scatter light, conferring a more or less opaque cloudy appearance on the composition which comprises them. On bringing the wax to its melting point, it is possible to render it miscible with oils and to form a microscopically homogeneous mixture but, on bringing the temperature of the mixture back to ambient temperature, recrystallization of the wax in the oils of the mixture is obtained, which recrystallization can be detected microscopically and macroscopically (opalescence).

[0202] A person skilled in the art will take care to choose the optional additives and their amounts so that they do not harm the properties of the compositions disclosed herein.

[0203] These additives can be present in the composition according to the present disclosure in an amount ranging from 0 to 20% by weight, with respect to the total weight of the composition.

[0204] Other than in the examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term "about." Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.

[0205] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

[0206] The following examples illustrate the present invention and should not be regarded in any way as limiting the invention.
